Sorry, htc has gone a way I will not go, no SD card, no removable battery, both of which made me go to Samsung, even though I always was a htc user and like the more solid, less plastic feeling of htc devices

that's bad news these two disadvantages you mentioned are considerable and well reasons to put sight off from htc. I tried both, the S4 and the one and decided for the htc despite sd slot issue und non removeable battery. The display is such a great one (holding it beside a s4 amoled display and you can't deny ) and haptic is unmatched. The sound comparison did the rest...I respect your point but i regret and never give up hope that you pay attention to the htc one after all
